Don't use "which". This command is only searching the PATH for the queried command. Only a builtin command can tell if another command is a builtin or not, this builtin is "type" with bash.

NOHUP(1) BSD General Commands Manual NOHUP(1)
NAME
nohup -- invoke a utility immune to hangups
SYNOPSIS
nohup [--] utility [arguments]
DESCRIPTION
The nohup utility invokes utility with its arguments and at this time sets the signal SIGHUP to be ignored. If the standard output is a ter-
minal, the standard output is appended to the file nohup.out in the current directory. If standard error is a terminal, it is directed to
the same place as the standard output.
Some shells may provide a builtin nohup command which is similar or identical to this utility. Consult the builtin(1) manual page.
ENVIRONMENT
The following variables are utilized by nohup:
HOME If the output file nohup.out cannot be created in the current directory, the nohup utility uses the directory named by HOME to create
the file.
PATH Used to locate the requested utility if the name contains no '/' characters.
EXIT STATUS
The nohup utility exits with one of the following values:
126 The utility was found, but could not be invoked.
127 The utility could not be found or an error occurred in nohup.
Otherwise, the exit status of nohup will be that of utility.
SEE ALSO
builtin(1), csh(1), signal(3)
STANDARDS
The nohup utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
BUGS
Two or more instances of nohup can append to the same file, which makes for a confusing output.
